Change in phonon dispersion with pressure

Click For Summary
SUMMARY

The discussion focuses on the analytical study of phonon dispersion in copper as it relates to pressure changes. Key resources mentioned include the Grueneisen parameters for understanding phonon dispersion dependence on pressure and the Birch-Murnaghan equation of state for modeling atomic spacing variations in copper. These concepts are essential for accurately modeling the crystal structure under varying pressure conditions.

PREREQUISITES
  • Understanding of phonon dispersion theory
  • Familiarity with Grueneisen parameters
  • Knowledge of the Birch-Murnaghan equation of state
  • Basic principles of crystallography
NEXT STEPS
  • Research the Grueneisen parameters specific to copper
  • Study the Birch-Murnaghan equation of state and its applications
  • Explore analytical methods for modeling phonon dispersion
  • Investigate the effects of pressure on atomic spacing in metals
USEFUL FOR

Researchers in materials science, physicists studying solid-state phenomena, and anyone involved in modeling the properties of metals under varying pressure conditions.

Hi,

I'm looking into how phonon dispersion changes with pressure analytically and need to know how the atomic spacing in copper changes with pressure in order to model the crystal. I can't find any helpful papers online :(

Any help would be appreciated

thanks

For phonon dispersion dependence on pressure, search for the Grueneisen parameters of copper. For lattice variation, search for Birch-Murnaghan equation of state of copper. I'm sure you will find these in literature.
